      Work Description: supratimdeka commented on issue #812: HDDS-1511. Space tracking for
Open Containers in HDDS Volumes. Contributed by Supratim Deka
URL: https://github.com/apache/hadoop/pull/812#issuecomment-492577036
 
 
   TestBlockOutputStreamWithFailures appears to be unpredictable - failures are intermittent.
   
   TestHddsDatanodeService appears to be broken.
   both are failing on trunk without the patch. Filed a jira for this issue.
   
   remaining tests are passing locally.

> For every HDDS Volume, track the space usage in open containers. Introduce a counter
committedBytes in HddsVolume - this counts the remaining space in Open containers until they
reach max capacity. The counter is incremented (by container max capacity) for every container
create. And decremented (by chunk size) for every chunk write.
> Space tracking for open containers will enable adding a safety check during container
create.
> If there is not sufficient free space in the volume, the container create operation can
be failed.
> The scope of this jira is to just add the space tracking for Open Containers. Checking
for space and failing container create will be introduced in a subsequent jira.
